No end in sight

Here is a brief run down of my last 3 weeks.   Post Wildflower has been 2 weeks of no activity beyond walking (horribly sick, ears totally clogged, like having ear plugs in.  Major congestion.  Wicked phlegmy cough).  Then last Saturday I got smacked in the head very hard by a softball. Very painful at the time but did not pass out.  Sunday was a sprint tri. (500, 12, and 4)  I went in to it not having done any exercise and having been sick for 2 weeks and not having slept well for 3 nights in a row. But I absolutely rocked it.  8:13, 41:02, and 36:59. Sunday night I started to feel a headache, but thought maybe I was just dehydrated from the race.  I'm not that great at hydrating for shorter things and I sweat a lot, even when it's cool out, which it was.  Monday my head was hurting a lot and then nausea hit.  Still went swimming though (I'm stubbornly stupid) and things felt really good while swimming, until after showering and nausea returned with headache. Had to go home from work i felt so shitty.  Felt like a bad migraine.  Tuesday was manageable, although still pain.  Felt better in the evening though, and biked 11 miles, felt ok while biking.  Wednesday wasn't good during the day.  But got out in the evening for a 5 mile trail run that was pretty good.  Thursday I went to the doctor.  Antibiotics for sinus infection, nasal spray for allergies and congestion. A different asthma inhaler for races.  And the possibility to get a cat scan if I wanted. Not going to get one.  Can't afford it (no insurance) symptoms are indicative of possible concussion, but nothing is scary, no vomiting, loss of consciousness, no memory issues, no change in behavior.  

I was given strict orders not to work out until I'm better.  And I cried sitting there in the doctors office.  (Then, 2 days later, I had to say goodbye to Kevin for 2 months, and an hour later go to a memorial service for my grandmother.  When it rains it pours?)

I have no idea when I'll be "better."  My head still doesn't feel right.  My ears are still plugged up from sinus crap.  Occasional cough.   I was already nervous about having enough time to get my mileage up to be ready for Canada.  If I miraculously feel better by the end of this week (unlikely), can I do it in 11 weeks?  And I feel like I'm losing everything I've spent the last 7 months working on.
